Bencina expenditure

The carburetor was installed the full kit ... and the advance is ok ... I had already anticipated all that ... but the same is an intense smell of benzine through the exhaust tube ... I do not know if it will be correct but they had told me that it may be that the valves do not have to be closing well so that for that reason the benzine escapes into the interior of the engine and it is not possible to burn completely ... this...??????

Actually, if it has something to do, because if the valves do not go correctly or open or close non -synchronized with the movement of the piston, it is possible that the MESCLA escapes CUDRA since so that a correct combustion is performed in the cylinder, it must find in the upper dead point and the two closed valves, if it does not accent well it escapes and produces this smell, to fix this problem, you also solve this problem. overlap that it is the moment in which the two valves are open and a sweep of the gases occurs, you want to have a decarbonized system and with this solutions.

Place your comment in practice ... and thanks to a good mechanic that I know we could solve this and a few more .... Thank you very much for your coooperation
